Application filed January 2, 1906. Serial No. 294,147.

of Milwaukee Wisconsin have invented a Leafand Cover Holder for Books, of which the following is a specification.-

My invention relates iJO'ClQVlCQS for holding books in open position without manual assistance, and particularly those books which are thick, narrow or stiff-backed and tend st-rongly'to close up of their own accord.

My invention is particularly applicable to books such as trade catalogues which are used by solicitors and commercial travelers to set their wares before prospective customers, and more particularly to looseleaf books having what is known as the telescopic back.

My invention will best be understood from the following description taken in connection with the accompanying drawings, in which- Figure 1 shows the simplest form of my book-holder, Fig. 2 shows a folding form of Fig. 1, Figs. 3 and L are respectively a side and an end elevation of another form of book-holder, Figs. 5 and 6 are respectively an end and a side elevation of a form of my invention having a leaf-holding attachment, Figs. 7 and 8 are respectively a plan and longitudinal central section through a form similar to that of Figs. 5 and 6 but having an attachment similar to that of Fig. 2. Fig. 9 is a side elevation of a book with my holder shown in Fig. 1 attached thereto to hold the book in open position, Fig. 10 is a perspectiveof a book showing the holder of Fig. 3 attached thereto, Fig. 11 is a side elevation of a book showing the holder of Figs. 5 and 6 in operative position thereon, and Fig. 12 is an elevation of the back of a book having a holder-attachment in accordance with my invention permanently secured thereto.

That form of my invention which is shown in Fig. 1 comprises a simple bar or strip of sheet metal or thin wood a, having a tongue 7) which is inserted into the crevice at the back of a book B (Fig. 9) between the cover and leaves for the purpose of holding the back thereof upright on the table A;

the ends of the bar a resting upon the table and preventing. the back from falling over laterally. In such position, the back being held vertical, the leaves will lie open in any desired position as illustrated in Fig. 9. In-

stead of a solid sheet or plate the holder might be made from a wire having at the center an offset the shape of the tongue 6, as willbe obvious.

Fig. 2 shows a folding form of Fig. 1 comprising three leaves a a a which are pivoted together on a screw 0, one of these leaves being inserted into the crevice at the back of the book and the whole folded up 111130 a small compass to put into the pocket.

The form shown in Figs. 3, L and 10 comprises a strip of sheet metal (Z bent into loop form as shown and having a bar a pivotally mounted on one lap thereof by a rivet f. This form is adapted especially for loose-leaf books having covers 13, B with telescopic backs g, 9 one of which overliesthe other. The free lap of the strip 65 is inserted at the back between the two folds 9, as shown in the drawing, and the bar 6 lies parallel to the book-cover when not in use, and when it is desired to hold the book open it is turned into the position d wherein it holds the back of the book upright in the same manner as illustrated in Fig. 9. This form can also be used by inserting the free lap of the strip d into the crevice at the end of the book-cover in the same manner as the tongue Z; of Fig. 1.

The form shown in Figs. 5 and 6 comprises a bar 7b which is arranged to be inserted into the crevice at the back between the cover and leaves in the same manner as the tongue I) in Fig. 1, said bar having one end bent up at right angles to form a tab 72. as shown; a post i pivoted to the tab il by a rivet j and having its upper end bent back obliquely in an olfset 2, said offset having a pair of pintle-lugs 11 at its opposite sides,

and a spring-clip k having perforated cars which turn on the lugs 2' The springclip is has further a spring-tongue 70 either cut out of the metal thereof as shown in the drawing, or else riveted to the free end of the clip as may be preferred, the end of the tongue 71: passing through an opening i in the post i. The rear end of the clip is is bent over to form a thumb-piece 70 It will be clear that the effect of the tongue 70 is to draw the clip 7s down, because when raised into the position 70 for instance, the tongue k will be sprung out from the body of the clip. Consequently the clip to acts as a finger or holder to hold down the leaves of the book on which it may rest. form may be used in either of two positions This shown respectively in Figs. 8 and 11. In Fig. 8 the book B lies open with the back upright and the clip 70 in the crevice be tween the leaves thereof. In Fig. 11 the back of the book is parallel to the table and the upper cover and some of the leaves turned back through 180, the post i being rotated into a position at right angles to that hown in Fig. 5 so as to enable the clip I: to overlie the open leaves at a point near the bend.

The form shown in Figs. 7 and 8 is similar to that of Fig. 6 except that there are added thereto a pair of strips m m which are pivoted upon a screw n fixed in an extension 0 formed on the end of the bar it beyond the tab it. The bars an), m fold up parallel to the bar it when the instrument is put in the pocket, and when in use they may be extended to hold the book in the position of Fig. 8, or may remain collapsed to hold it in the position of Fig. 11.

In Fig. 12 is shown a book with a holder permanently attached thereto, the holder consisting of two bars 79, p which are pivoted upon rivets q on the back of the book. The bars 7), 2) fold up against the bookcover as shown by the dotted lines when not in use, and when it is to be held open the bars p, p are extended to hold the bookcover upright on the table as shown in Fig. 9.

. From the above description it will be clear that my holder is not confined to any special form of detail but is subject to many changes and modifications whileretaining the principle thereof.

Having thus described my invention, what 7 v I claim as new and desire to secure by Letters Patent, is:

1. A device for holding ,books in open position comprising a fiat bar adapted to be inserted into the back between the outer cover and binding of the book projecting at one end of the back, and wings on said bar extending at right-angles to said bar beyond the sides of the back and lying in the plane:

of the back when said bar is so inserted. V 2. A device for holding books in open position comprising'a fiat bar adapted to be inserted into the back between the outer cover and binding; of the bookprojecting at one end of the back, and wings on said bar Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, Washington, D.
